To all whmn it 'mcty concern:

Be it known that I, SARAH H. KENDALL, a citizen of the United States,and a resident of Davenport, in the county of Scott and State of Iowa,administratrix for the estate of AMOS M. KENDALL,deceased, do herebydeclare that said AMOS M. KENDALL, who was a citizen of the UnitedStates, and a resident of Davenport, in the county of Scott and State ofIowa, did invent certain new and useful Improvements in Brakes for Cars,of which the following is a full, clear, and exact description.

The object of said invention is to provide a simply-constructed andefiective handle for the shafts of mechanical brakes for cars, andparticularly for passenger-cars, whether vestibule or otherwise, whichwhen not in use lies back against the wall of the car in such manner asto leave the platform free and which because of the great leverage itsconstruction makes possible is capable of easy operation with one hand.This is accomplished by the means hereinafter fully described, and asparticularly pointed out in the claims.

In the drawings, Figure 1 is a front view of said invention. Fig. 2 is ahorizontal section taken on dotted line 2 2, Fig. 1, showing the pawl inengagement with the ratchet. Fig. 3 is a similar view showing the pawlreleased from the ratchet. Fig. 4 is a front view of the end portion ofthe lever nearest the brake-shaft, showing the shell thereof inlongitudinal central section. view showing the lever in a positionopposite to that shown in Fig. 1.

In the drawings, A represents a suitable plate, preferably ofrectangular proportions, which is secured to the end wall of the car atsuch height above the platform that the handle of the mechanical brakesupported thereby will be within convenient reach of train-hands.Projecting centrally from this plateis a bracket a, which provides asuitable bearing for the upper end of the brake-shaft B, and projectingfrom the upper right-hand corner of said plate is a release-lug b, theextent of whose projectionis considerably less than that of lug a,substantially as shown. The part 0 of the shaft B journaled in thebearing-boss a. is preferably slightly greater Fig. 5 is a plan indiameter than the portion below the same, and this enlarged portionextends a short distance above its bearings and serves as a journal forthe annular boss or sleeve (2, secured to the contiguous end of theplate D, forming the under side of the contiguous hollow end portion 6of the lever E. Immediately above sleeve d shaft B is reduced indiameter to form a seat f for the-segmental span or sickleshaped arm gof the trip G, as will here inafter more fully appear, and above thisseat said shaft is provided with a ratchet F. The

upper end of the shaft extends slightly above the ratchet F and ispreferably reduced in diameter and fits into the socket h, formed in aboss made integral with and arisingfrom the upper side of the contiguousend of the hollow portion 6 of lever E. 7

Arising vertically from the end plate D is a vertical post H, in theside of which facing the ratchet it is provided with alongitudinally-extending open bearing m, the entrance to'which is lessthan the diameter thereof, and journaled in this open bearing m is thepintle n of the wing I. Wing I extends from its pintle out through therestricted entrance of the open bearing m and increases in width as itapproaches the ratchet and has in its vertical edge an open bearing,similar to that in lug H, in which the pintle of the pawl J isjournaled. The pawl J extends a suitable distance toward the rear of thelever and is so shaped that its rear vertical surface is normally incontact with the beveled surface of the contiguous vertical edge of thearm I, (to the rear of the open bearing therein,) and its heel on theopposite side is provided with a V-shaped projection or tooth o,whichengages the ratchet, substantially as shown. Pawl J is kept bearingagainst the ratchet by the pressure of a leaf-spring K, the contiguousend of which presses forward against the rear surface of the wing I, andthe opposite end of said spring is secured and held'between' lugs lo7o,projectin g vertically from said plate D, near the end thereofopposite the brakeshaft. V

The construction of said invention, as hereinbefore described, is suchthat when the lever is moved from right to left the pawl engaging theratchet will turn shaft B in the same direction; but when the levermoves from left to right it will ride over said ratchet preparatory toobtaining a fresh grip upon the same when it arrives at the limit of itsleft-to-right movement. When it is desired to release or disengage thepawl from the ratchet to permit the shaft to reverse, pressure upon thetrip is brought to bear either by hand or in the manner hereinafterreferred to. Arm 9 projects from and forms the fulcrum or pivot for thebody of trip G, which latter is block-shaped and has the outer verticalside thereof rectangular. The portion of this body above the plane ofthe arm g is made thicker, and its inner surface operates as apresser-foot r, that normally rests against the front vertical surfaceof wing I. Projecting horizontally and longitudinally from the loweredge of this trip-body in a plane slightly below that of arm g is ashort handle or arm R. Now when it is desired to release the pawl fromthe ratchet, handle R of the trip is when the lever is in the positionshown in Fig. 1 pushed to the rear, thus causing the presser-foot r tobear against and move arm I to the rear and carrying the pawl J out ofengagement with the ratchet. The same result will be accomplished bythrowing the lever around to the limit of its movement from left toright and causing the outer surface of the body of the trip to come incontact with and be depressed by the releasing-lug g of plate A.

The sides of the end portion 6 of the lever E in which the movablemechanism carried thereby is housed consists of a comparatively thinshell, and the longitudinal vertical sides of the same are continuousaround the shaft B to form an end wall. A portion of this curved endwall extends down to form the drop wall or apron s, which surrounds andholds arm 9 of the trip in its seat and overlaps a portion of the sleeve(1. The side wall of portion 6 of said lever E where the body of thetrip is located is cut away to accommodate the same.

An important feature of this invention is the fact that, aside fromsecuring the plate D to the under side of the portion 6 of the lever Eby rivets, bolts, or any other suitable manner, very little, if any,machine-work is necessary in the construction ofsaid improved lever andevery part of the same is so constructed that it can be removed andreplaced by inexperienced persons easily and quickly.

What I claim, and desire to secure by Letters Patent for and on behalfof the estate of the said AMos M. KENDALL, deceased, is-

1. A brake for cars comprising a lever, a shaft having a ratchetthereon, and a springcontrolled double-jointed pawl connected to saidlever and engaging said ratchet.

2. A brake for cars comprising a lever, a shaft having a ratchetthereon, a spring-controlled double-jointed pawl connected to said leverand engaging said ratchet, and a trip for disengaging said pawl fromsaid ratchet.
